the FFT is computed from of a block of data which is not periodic. To correct this problem appropriate measured with an impact hammer and accelerometer.
The Fast Fourier Transform (FFT) and the power spectrum are powerful tools for analyzing and measuring signals from plug-in data acquisition (DAQ) devices.
